Title: Secure network method and apparatus
Inventor: FOLLENDORE III ROY D
IPC: G06F21/60
Filed: 1993-07-23
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for ensuring the security of messages communicated on a network.  The system employs different levels of security to ensure that communication integrity is not breached.          A user must first enter a valid password to clear the access control subsystem.   The sending user must also possess valid cryptographic information and belong to a particular organization and/or be located at a particular device in order to encrypt a plain text message that is to be transmitted over the network.  The device and organization information,  along with receiving user information specified by the sending user, will then be grouped into a header which will be appended to the outgoing encrypted message.  In order to receive a transmitted message, a receiving user must be the particular receiving user and be part of the particular group specified by the  sending user,  and must be attempting to receive the communication at the device specified in the  message  header.    If  these  conditions  are  satisfied, cryptographic information must be entered into the system in order to decrypt the message,  resulting in the original plain text message.

Title: Process for the production of a pyrogen-free fructan which is readily water-soluble as well as renal diagnostic agent containing such a fructan
Inventor: NITSCH ERNST
IPC: A61K36/8962
Filed: 1992-01-21
Abstract: A process is described for the production of a readily water-soluble fructan as well as a well-tolerated renal diagnostic agent containing such a fructan. In the process an aqueous fructan extract obtained from parts of plants is ultrafiltered over a first membrane which retains carbohydrates and proteins with a higher molecular weight but which allows passage of fructan and the filtrate obtained in this way is then filtered in a second ultrafiltration through a membrane which retains fructan but which allows passage of salts and low-molecular substances such as monosaccharides and oligosaccharides. The fructan obtained in this way is used as a renal diagnostic agent together with physiologically tolerated buffer substances at an osmolality which corresponds to that of blood and which has a pH of 5.0 to 7Ø

Patent CA-2118410-A1 (CA)
Inventor: ALAJAASKI TIMO
IPC: B01D29/11
Filed: 1993-04-08
Abstract: The present invention relates to an apparatus for treating fiber suspension. Theapparatus in accordance with the present invention is especially suitable for screening pulps and also for thickening. More accurately, the apparatus relates to the pulse member construction of the screen or thickener being used. It is characteristic of all pulse members in accordance with the prior art that when the capacity of the screening apparatus in increased, for example, by using greater pressure differences or the cleanliness of the accept is increased by decreasing the size of the perforations or slots, this results in a situation, in which the screen cylinder tends to clog. The problem is thus keeping the screen cylinder clean, which is a precondition for optimizing other features in the screening. The present invention relates to a pulse member (P) of the screening apparatus, which is characterized in that the screen surface is subjected thereby with members (60) to a pulse cleaning the screen surface without a chance to allow the pressure effect "escape" past the area being cleaned. It is also typical of the pulse member in accordance with the present invention that the higher the consistency of the fiber matting is or the worse the screen surface is clogged, the stronger the pulse cleaning the screen surface is.

IPC: A01F25/14
Filed: 1994-05-05
Abstract: A thermoplastic tube for in-field storage or packaging of bales of agricultural products is disclosed.      The tube combines high puncture resistance with an exceptional stretchability, elasticity and good slip properties. The circumference of the tube can be expanded by at least 15% without tearing when stretched in the transverse direction. The tube also shows no substantial permanent deformation 2 hours after being so stretched for a period of time not exceeding 30 minutes and released.      Before feeding a bale, the tube is stretched radially to facilitate the insertion and accommodate bales larger than original diameter of the tube. When regaining the original size, the tube wraps up tightly the bales reducing the amount of air trapped in the tube. Since the tube can be enlarged to a variable extent, it may accommodate bales of different shapes and sizes.

Title: Decision Circuit Operable at a Wide Range of Voltages
Inventor: MINAMI YOICHIRO
IPC: G01R19/165
Filed: 1994-12-23
Abstract: A decision circuit compares an input voltage with a reference voltage and judges whether the input voltage is at least equal to the reference voltage. A controller in the decision circuit detects whether the input voltage or reference voltage is at least equal to the setting voltage. When both the input voltage and the reference voltage are lower than a setting voltage, which represents an operating voltage of the decision circuit, a first bias-supply circuit adds a predetermined bias voltage to the input voltage and supplies a level-shifted input voltage to the decision circuit. Similarly, a second bias-supply circuit adds the predetermined bias voltage to the reference voltage and supplies a level-shifted reference voltage to the decision circuit. Therefore, the decision circuit compares the level-shifted input voltage with the level-shifted reference voltage.
